Would love to see the font as a larger size on #21 and #23 as this graphic may appear on small eye dropper bottles and still need to be read. Love where you are going with it is as well. We tend to like the drop to be orange, and anything to do with the plant green. Would love to see any other ideas you have as well!
After looking through all the designs again the only other comment I would have besides the size of text would be that I would love to see what creative idea you would have of integrating the tree/leaf into the design of #21 to show that it is coming from or part of something natural.
